Useful:

• Chemical Classes: Metals -> Metals, Inorganic Compounds
• Canonical SMILES: C(=O)[O-].C(=O)[O-].[Ca+2]
• Recent ClinicalTrials: Evaluation of the Ocular Safety of Calcium Formate in Normal, Healthy Female Subjects
• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed.
• Effects of Short Term Exposure: The substance is irritating to the eyes.
• Hydrogen Supply for Catalytic Fast Pyrolysis: Calcium formate is employed as a hydrogen source in catalytic fast pyrolysis experiments aiming to increase the production of monocyclic aromatic hydrocarbons (MAHs) and suppress the formation of polycyclic aromatic hydrocarbons (PAHs). It exhibits the best ability among the tested co-feeders (methanol, polyethylene terephthalate) to promote the conversion of biomass into MAHs. The presence of calcium formate enhances the yields of MAHs while reducing PAH formation during pyrolysis.
• Use as Accelerator in Cement Paste: Calcium formate is a common organic additive in cementitious systems. Calcium formate serves as an accelerator for the hydration of C3S (tricalcium silicate) in cement paste. It promotes the production of ettringite and C-S-H (calcium silicate hydrate) at early ages, influencing the physicochemical and mechanical properties of pozzolanic cement pastes.; CF is also commonly applied in gypsum plasters. It is known to improve the adhesion of the plaster on plastic and metal surfaces and to prevent sodium sulfate efflorescence caused by subsequent moisture.
• Dietary Supplement: Calcium formate is investigated as a potential dietary calcium supplement due to its water-soluble salt nature. Plasma concentration studies in human subjects show a brisk increase in formate levels following oral administration, with subsequent decline to baseline levels within hours. Repeated use of calcium formate as a dietary supplement is not expected to lead to progressive accumulation of formate due to its short half-life.
• Production Methods: 1. Reaction with Dilute Formic Acid and Calcium Carbonate/Hydroxide: Calcium formate is produced by reacting dilute formic acid with calcium carbonate or calcium hydroxide to generate a calcium formate solution.; 2. Aqueous Phase Reaction: Calcium formate can be produced in the aqueous phase by various reactions:; Reaction of calcium hydroxide with formaldehyde in the presence of hydrogen peroxide.; Reaction of calcium peroxide with formaldehyde.; Molar ratios of reactants are specified, such as 1:2:1-1.2 for CaO or Ca(OH)2 to H2CO to H2O2, and 1:2 for CaO2 to H2CO.; 3. Reaction with Carbon Monoxide:; Calcium formate can be produced at high pressure and temperature by reacting calcium hydroxide with carbon monoxide, typically at 180掳C and 35 atm.; 4. Reaction with Calcium Chloride and Formic Acid: Calcium formate can be produced from calcium chloride and formic acid.; 5. Natural Production from Calcium Hydroxide and Carbon Dioxide:; Calcium formate can naturally form by reacting calcium hydroxide with carbon dioxide.; This reaction occurs in animal waste, where calcium hydroxide reacts with carbon dioxide to produce calcium carbonate and formic acid, followed by the formation of calcium formate from the reaction of formic acid with calcium hydroxide.
